OPEN 2018
Atlanta, Georgia
Project Term:
05/02/2019 - 05/01/2024

Technology Description:

The Georgia Tech Research Corporation (GTRC) will develop a new approach to internally cool permanent magnet motors. The technology could dramatically improve electric motors’ power density and reduce system size and weight. To do so, the team will integrate motor and drive electronics into a unique system packaging incorporating an embedded advanced thermal management system. They will also develop wide bandgap power electronics packaging to enable high power density operations at higher temperature. The new design could substantially increase the power and torque density above the state of the art and enable more energy-efficient electric trucks, buses, and, potentially, aircraft.

Potential Impact:

The IPM motor will provide transformative opportunities in electrification of ground and air transport sectors.


The proposed concept will enhance economic and energy security of the U.S. through enabling a technological lead in electrification of ground and air transportation.


These innovations will reduce greenhouse gas emissions due to more electrification, and improve energy efficiency of transportation systems using electric motors.


Electrical motors currently account for 47% of global electricity consumption. High power density motor development will positively impact many other motor applications for compact systems. High performance, low cost power electronics would enable significant efficiency gains across the economy.
